Easy — logic-grid deduction puzzle
Only a few pencilled notes are left to show which room, piano and fault went with Thomasina, Vivian, Winston and Agatha.
It was a quiet afternoon at the conservatoire, in the gap between lessons. Now and then a single chord rang out from behind a closed door as someone tried a piano. Four tuners came in that day: Thomasina, Vivian, Winston and Agatha. The practice rooms ran in a row down the long corridor, from the first room by the stairs to the last room at the far end. Each tuner went into one room. Each room held a different kind of piano, and each piano had a different thing wrong with it. All that is left of the day is a handful of pencilled notes in the appointment book. Can you piece their rounds back together?
